Stevie Nicks tells ABC News Radio that she's especially excited about the December 31 concert, because it will be a big communal celebration between the band and the audience.

"We get to get dressed up and go on stage and actually be at a really huge New Year's Eve party," the singer says. "You don't even have to find the party. It's found you at this point."

Nicks notes that playing on New Year's Eve is "always fun, because everybody is super excited." She adds that that energy, in turn, "really rubs back off on the band."

Stevie reveals that Fleetwood Mac also has another private concert in Las Vegas scheduled for January 8. These three shows are the first the band will play since they announced in October that bassist John McVie had been diagnosed with cancer, which forced the cancellation of a planned tour of Australia and New Zealand.

Nicks suggests that the concerts will be "really good for John," because she feels it will help him "get back on the treadmill" after undergoing treatment for the disease. Fleetwood Mac currently has no other performances on its schedule.
